Secure your number and SIM with Line Lock by Visible
What is Line Lock?
Line Lock protects your service from unauthorized activity related to port-outs and SIM swaps. When Line Lock is toggled to Locked, the following become restricted:
Port-outs – While Line Lock is toggled to Locked, you will not be able to generate a port-out PIN nor will you be able to port your line of service to a new carrier. In order to do so, you will need to toggle Line Lock to Unlocked.
This is to prevent someone unauthorized from moving your line of service to a new carrier.
SIM changes – While Line Lock is toggled to Locked, you will not be able to pair your Visible service with a new eSIM or pSIM.
This is to prevent someone unauthorized from taking control of your line of service on a device that you do not control.
Note:
- After toggling Line Lock to Unlocked, it will take 30 minutes before all restrictions have been lifted. After 30 minutes, you will be able to make any needed SIM changes or port-out your phone number.
- An unlock time will appear underneath the Line Lock section of Number Security. The unlock time will let you know when all restrictions have been lifted.
- Example: If you select Unlock at 8:07 am, the unlock time will show 8:37 am.
- Emails and SMS notifications will be sent each time you change your Line Lock setting.
- Members with lapsed accounts still have the ability to change their Line Lock status.
